This study was designed to explore the influence of long-term corneal contact lens (CL) wearing on the stability and quality of tear film in Qinghai. Thirty subjects with CL over five years and thirty myopia subjects without CL as control were recruited in our study. Basic tear secretion test, tear film break-up time (TBUT), and corneal fluorescein staining were determined. For further evaluati...

The deformation of a leaf is the aggregation of the deformation of all the cells on the leaf. Mesophyll cells and vascular bundle cells have distinctly different degree of rigidity for shrinkage. In order to simulate the deformation of an autumn leaf realistically we need the realistic venation distribution of the leaf. We modify Runions’s technique [Runions et al. 2005] by increasing the growi...

OBJECTIVE The objective of this study was to analyze the lung cancer related SNPs (Single Nucleotide Polymorphisms) and CNVs (copy number variations) with SNP microarrays, as well as to identify the CNV related genes and functions. MATERIALS AND METHODS The GSE29172 SNP array data were downloaded from Gene Expression Omnibus, including 100%, 30%, 50%, 70% cancer samples, and the mixture is ma...

Soil soluble nickel (Ni) concentration is very important for determining soil Ni toxicity. In the present study, the relationships between soil properties, total and soluble Ni concentrations in soils were developed in a wide range of soils with different properties and climate characteristics. The multiple regressions showed that soil pH and total soil Ni concentrations were the most significa...
